Abstract

그의 한면 이상에 라미네이팅된 스펀본디드 폴리프로필렌 섬유 시이트(10)을 갖는 멜트 블로운 폴리프로필렌 섬유웹(20)으로 이루어진 조절된 다공도의 복합체 시이트는 2층 복합체 시이트를 제조할 경우에는 멜트 블로운 섬유웹을 비가열 탄성롤(2)의 반대에서 작동하는 140 내지 170℃로 가열된 금속 롤(1)과 접촉시키고, 3층 복합체 시이트를 제조할 경우에는 가열 금속 롤라 접촉하는 스펀본디드 웹이 섬유 당 6미만의 dtex값을 갖는 방식으로 성분 웹의 어셈블리를 캘린더링시킴으로서 제조된다. 이러한 복합체 시이트는 약 5내지 75초의 걸리-힐다공도, 뛰어난 기계 및 인열 강도, 높은 수증기 투과율 및 낮은 액체 물 투과율을 갖는다. 이 들은 특히 하우스랩 시이트 및 살균 화장용 시이트에 적합하다. 살균 포장 분야에 있어서, 이들은 동일한 목적으로 사용되는 의료용 페이퍼보다 훨씬 우수하다.
